Projection Theorems for -Intermediate Dimensions

Lara Daw, Najmeddine Attia

-intermediate dimensions interpolate between Hausdorff and box-counting dimensions by restricting admissible coverings to scale windows of the form . Using a family of…

Multifractal analysis and Erdös-Rényi laws of large numbers for branching random walks in

Najmeddine Attia, Julien Barral

We revisit the multifractal analysis of -valued branching random walks averages by considering subsets of full Hausdorff dimension of the standard level sets, over each infin…

On a class of Hausdorff measure of cartesian product sets

Hajer Jebali, Riheb Guedri, Najmeddine Attia

In this paper, we study, in a separable metric space, a class of Hausdorff measures defined using a measure and a premeasure . We discuss a Hausdorff…

A note on the generalized Hausdorff and packing measures of product sets in metric space

Rihab Guedri, Najmeddine Attia

Let and be two Borel probability measures on two separable metric spaces $\X$ and $\Y$ respectively. For be two Hausdorff functions and , we introduce and i…

On the Hewitt Stromberg dimension of product sets

Najmeddine Attia

In this paper, we construct new multifractal measures, on the Euclidean space , in a similar manner to Hewitt-Stomberg measures but using the class of all -dimensi…

A multifractal formalism for Hewitt-Stromberg measures

Najmeddine Attia, Bilel Selmi

In the present work, we give a new {\it multifractal formalism} for which the classical multifractal formalism does not hold. We precisely introduce and study a multifractal formal…

Hausdorff and packing spectra, large deviations, and free energy for branching random walks in

Najmeddine Attia, Julien Barral

Consider an -valued branching random walk (BRW) on a supercritical Galton Watson tree. Without any assumption on the distribution of this BRW we compute, almost surely and si…
